Step-by-Step Code Implementation of Python Django Online Voting System<\/h3>\n
1. Project Initialisation<\/h4>\n
- \n
- The first command initializes a new Django project named VotingSystem<\/strong>. The startproject command creates a new directory with the project name.<\/li>\n
- The second command changes the directory to the project folder.<\/li>\n
- The third command initializes a new Django app named vote in the same directory. It sets up the basic structure for the projects.<\/li>\n<\/ul>\n
django-admin startproject VotingSystem\r\ncd VotingSystem\r\npython manage.py startapp vote\r\n<\/pre>\n
2. Setting Up Models<\/h4>\n
- \n
- user<\/strong>: It is a foreign key referencing the User<\/strong> model from django.contrib.auth.models<\/strong>. This represents the user who cast the vote.<\/li>\n
- candidate<\/strong>: It\u2019s referencing the Candidate<\/strong> model, which represents the candidate for whom the vote is cast.<\/li>\n
- timestamp<\/strong>: It automatically sets the timestamp to the current date and time when a Vote<\/strong> object is created.<\/li>\n<\/ul>\n
from django.db import models\r\nfrom django.contrib.auth.models import User\r\n\r\n\r\nclass Candidate(models.Model):\r\n name = models.CharField(max_length=100)\r\n party = models.CharField(max_length=100)\r\n bio = models.TextField()\r\n\r\n\r\n def __str__(self):\r\n return self.name\r\n\r\n\r\nclass Vote(models.Model):\r\n user = models.ForeignKey(User, on_delete=models.CASCADE)\r\n candidate = models.ForeignKey(Candidate, on_delete=models.CASCADE)\r\n timestamp = models.DateTimeField(auto_now_add=True)\r\n\r\n\r\n def __str__(self):\r\n return f\"{self.user.username} voted for {self.candidate.name}\"\r\n<\/pre>\n3. Making Migrations<\/h4>\n
- \n
- makemigrations<\/strong>: Makes migrations based on the changes detected in the models. Migrations are how Django stores changes to the models.<\/li>\n
- migrate<\/strong>: This command applies the migrations to the database, creating the tables and columns.<\/li>\n<\/ul>\n
python3 manage.py makemigrations \r\npython3 manage.py migrate\r\n<\/pre>\n
4. Defining Views<\/h4>\n
- \n
- @login_required<\/strong> : This ensures that certain views (like vote and results) are only accessible to authenticated users.<\/li>\n
- Forms (UserRegisterForm and VoteForm):<\/strong> These forms are used for handling user registration and voting, which are crucial for validating and processing user input.<\/li>\n
- Models (Candidate and Vote):<\/strong> These models are imported from .models<\/strong>, suggesting they reside in the same app as these views.<\/li>\n<\/ul>\n
from django.shortcuts import render, redirect\r\nfrom django.contrib.auth import login, authenticate\r\nfrom django.contrib.auth.decorators import login_required\r\nfrom .forms import UserRegisterForm, VoteForm\r\nfrom .models import Candidate, Vote\r\n\r\n\r\ndef home(request):\r\n return render(request, 'vote\/home.html')\r\n\r\n\r\ndef register(request):\r\n if request.method == 'POST':\r\n form = UserRegisterForm(request.POST)\r\n if form.is_valid():\r\n form.save()\r\n username = form.cleaned_data.get('username')\r\n password = form.cleaned_data.get('password1')\r\n user = authenticate(username=username, password=password)\r\n login(request, user)\r\n return redirect('vote')\r\n else:\r\n form = UserRegisterForm()\r\n return render(request, 'vote\/register.html', {'form': form})\r\n\r\n\r\n@login_required\r\ndef vote(request):\r\n if request.method == 'POST':\r\n form = VoteForm(request.POST)\r\n if form.is_valid():\r\n vote = form.save(commit=False)\r\n vote.user = request.user\r\n vote.save()\r\n return redirect('results')\r\n else:\r\n form = VoteForm()\r\n candidates = Candidate.objects.all()\r\n return render(request, 'vote\/vote.html', {'form': form, 'candidates': candidates})\r\n\r\n\r\ndef vote_list(request):\r\n candidates = Candidate.objects.all()\r\n return render(request, 'vote\/vote_list.html', {'candidates': candidates})\r\n\r\n\r\n@login_required\r\ndef results(request):\r\n candidates = Candidate.objects.all()\r\n votes = Vote.objects.all()\r\n vote_count = {candidate: votes.filter(candidate=candidate).count() for candidate in candidates}\r\n return render(request, 'vote\/results.html', {'vote_count': vote_count})\r\n<\/pre>\n5. Setting URLs<\/h4>\n
- \n
- The urlpatterns<\/strong> list contains URL pattern definitions.<\/li>\n
- ‘ ‘ directs to the home<\/strong> view function.<\/li>\n
- ‘register\/’<\/strong> is responsible for user registration as it renders the registration form register.html.<\/strong><\/li>\n
- \u2018vote\/’<\/strong> manages the voting process by rendering the voting form vote.html.<\/li>\n
- ‘results\/’<\/strong> displays voting results.<\/li>\n<\/ul>\n
from django.urls import path\r\nfrom . import views\r\n\r\n\r\nurlpatterns = [\r\n path('', views.home, name='home'), # Home page view\r\n path('register\/', views.register, name='register'),\r\n path('vote\/', views.vote, name='vote'),\r\n path('results\/', views.results, name='results'),\r\n]\r\n<\/pre>\n6. Creating Templates<\/h4>\n
base.html:-<\/strong><\/p>\n
- \n
- This template uses Django to create a dynamic web page for a voting system.<\/li>\n
- A responsive navigation bar is provided with links to the home, register, vote, and results pages.<\/li>\n
- URLs for these links are dynamically generated using Django’s {% url %}<\/strong> template tag.<\/li>\n
- The main content and footer areas are defined using Django’s {% block %}<\/strong> tags.<\/li>\n
- JavaScript libraries such as jQuery, Popper.js, and Bootstrap’s JS are included from CDNs to enable interactivity and responsive design.<\/li>\n<\/ul>\n
<!DOCTYPE html>\r\n<html>\r\n<head>\r\n <title>{% block title %}Voting System{% endblock %}<\/title>\r\n {% load static %}\r\n <link href=\"https:\/\/stackpath.bootstrapcdn.com\/bootstrap\/4.5.2\/css\/bootstrap.min.css\" rel=\"stylesheet\">\r\n <link href=\"{% static 'vote\/style.css' %}\" rel=\"stylesheet\">\r\n<\/head>\r\n<body>\r\n <nav class=\"navbar navbar-expand-lg navbar-custom fixed-top\">\r\n <a class=\"navbar-brand\" href=\"{% url 'home' %}\">TechVidvan-Voting System<\/a>\r\n <button class=\"navbar-toggler\" type=\"button\" data-toggle=\"collapse\" data-target=\"#navbarNav\" aria-controls=\"navbarNav\" aria-expanded=\"false\" aria-label=\"Toggle navigation\">\r\n <span class=\"navbar-toggler-icon\"><\/span>\r\n <\/button>\r\n <div class=\"collapse navbar-collapse\" id=\"navbarNav\">\r\n <ul class=\"navbar-nav mr-auto\">\r\n <li class=\"nav-item\">\r\n <a class=\"nav-link\" href=\"{% url 'register' %}\">Register<\/a>\r\n <\/li>\r\n <li class=\"nav-item\">\r\n <a class=\"nav-link\" href=\"{% url 'vote' %}\">Vote<\/a>\r\n <\/li>\r\n <li class=\"nav-item\">\r\n <a class=\"nav-link\" href=\"{% url 'results' %}\">Results<\/a>\r\n <\/li>\r\n <\/ul>\r\n <\/div>\r\n <\/nav>\r\n <div class=\"container\">\r\n {% block content %}{% endblock %}\r\n <\/div>\r\n {% block footer %}{% endblock %}\r\n <script src=\"https:\/\/code.jquery.com\/jquery-3.5.1.slim.min.js\"><\/script>\r\n <script src=\"https:\/\/cdn.jsdelivr.net\/npm\/@popperjs\/core@2.5.4\/dist\/umd\/popper.min.js\"><\/script>\r\n <script src=\"https:\/\/stackpath.bootstrapcdn.com\/bootstrap\/4.5.2\/js\/bootstrap.min.js\"><\/script>\r\n<\/body>\r\n<\/html>\r\n<\/pre>\nregister.html:-<\/strong><\/p>\n
- \n
- {% extends “vote\/base.html” %},<\/strong> this block shows that it extends base.html.<\/li>\n
- It includes external CSS for styling different pages of the Project.<\/li>\n
- This template uses the Django template to dynamically generate a form for registering new users to vote.<\/li>\n<\/ul>\n
<{% extends \"vote\/base.html\" %}\r\n\r\n\r\n{% block title %}Register - Online Voting System{% endblock %}\r\n\r\n\r\n{% block content %}\r\n<h2>Register<\/h2>\r\n<form method=\"post\" class=\"mt-3\">\r\n {% csrf_token %}\r\n <div class=\"form-group\">\r\n {{ form.as_p }}\r\n <\/div>\r\n <button type=\"submit\" class=\"btn btn-success\">Register<\/button>\r\n<\/form>\r\n{% endblock %}\r\n<\/pre>\nvote_list.html:-<\/strong><\/p>\n
- \n
- The {% for candidate in candidates %}<\/strong> loop generates list items for each candidate, displaying their name and party.<\/li>\n
- The {% empty %}<\/strong> tag provides a fallback message, “No candidates available,” if there are no candidates to display.<\/li>\n<\/ul>\n
<!DOCTYPE html>\r\n<html>\r\n<head>\r\n <title>Voting List<\/title>\r\n<\/head>\r\n<body>\r\n <h1>Voting List<\/h1>\r\n <ul>\r\n {% for candidate in candidates %}\r\n <li>{{ candidate.name }} - {{ candidate.party }}<\/li>\r\n {% empty %}\r\n <li>No candidates available.<\/li>\r\n {% endfor %}\r\n <\/ul>\r\n<\/body>\r\n<\/html>\r\n<\/pre>\nvote.html:-<\/strong><\/p>\n
- \n
- {% extends “vote\/base.html” %}<\/strong> extends the base template, maintaining consistency across the pages<\/li>\n
- {% block title %}Vote – Online Voting System{% endblock %}<\/strong> sets the page title to “Vote – Online Voting System”.<\/li>\n
- The form, enclosed within <form><\/strong> tags include a form-group div displaying the form fields with {{ form.as_p }}.<\/strong><\/li>\n<\/ul>\n
{% extends \"vote\/base.html\" %}\r\n\r\n\r\n{% block title %}Vote - Online Voting System{% endblock %}\r\n\r\n\r\n{% block content %}\r\n<h2>Vote<\/h2>\r\n<form method=\"post\" class=\"mt-3\">\r\n {% csrf_token %}\r\n <div class=\"form-group\">\r\n {{ form.as_p }}\r\n <\/div>\r\n <button type=\"submit\" class=\"btn btn-primary\">Submit Vote<\/button>\r\n<\/form>\r\n{% endblock %}\r\n<\/pre>\nPython Django Online Voting System Output<\/h3>\n
